Cisco Firewall :: ASA 5505 Creating Interface Vlan In Firewall

May 3, 2011

I have been working with ASA 5510,20,40,80 but not with 5505 this vlan and its interfaces are quite confusing.Just want to know how it works and its connectivity to Cisco Switch.Do i have to put the interface of the switch in the same vlan as i am creating the interface vlan in firewall ?Now the switch port connecting to this Eth1 interface should also be in the same vlan ? i.e vlan3 ?? or it will be in trunk ? The default configuration shows the eth0 with no access vlan and interface eth1 with access vlan 2... does it mean the eth0 is in vlan1 ? (Nativ Vlan ) ???

How do i tell my firewall to start listen also on another outside ipadress assigned by my ISP? I have it used on other firewall right now. So my steps would be shutting down ip address assignment off old firewall interface. Assign that ip address to ASA5510 outside interface and configure NAT.

ASA 5505 - Can't Ping Any VLAN Interface

Aug 9, 2012

I'm trying to set up a Guest VLAN for wireless at a client site, and I feel like I'm missing something small in the configuration, since I can't ping any of the VLAN interfaces from my laptop when the address is statically set to something in the 172.20.100.x range.

I've pasted the configs for the ASA 5505 and the 6 switches below for convenience. Near as I can tell, all should be well. The ports are in trunking mode, the "show cdp neighbors" command returns the proper information, VLAN 100 exists on all the switches, etc.

Code:
ASA Version 7.2(4)
!
hostname ASA
domain-name xxxx.local
enable password Cj3LF.ehxXN3xVkxWcxd encrypted
passwd Cj3LF.ehxXN3xVkWcxd encrypted

Cisco Firewall :: Failover ASA 5505 - Setup Second Inside Interface On Firewall?

Feb 19, 2012

I have a Cisco ASA 5505 in our office. We are currently using Interface 0 for outside and 1 for inside. We only have 1 Vlan in our environment. We have two three switches behind the firewall. Today the uplink to Interface 1, to the firewall, on the switch went bad. I want to setup a second inside interface on the firewall and configure it as failover incase this happens again. I want to attach it to the other switch. Can I do this? If so, what do I need to do? would it only be a passive/standby interface?

Cisco Firewall :: 6500 FWSM Vlan Interface

Jan 29, 2012

Is it possible for me to create 2 vlan interfaces on the 6500 and have them both in the same subnet?
 
For a specific customer requirement I would like to have a vlan interface on the 6500 as default gateway, sat in it's own vrf, and then route all traffic inbound and outbound to this vlan through the FWSM interface, preferably in the same subnet. I don't think this will be possible so just looking for confirmation either way.
 
As I will be running EIGRP between a pair of central 6500's and 2 remote offices it will make things much easier for me advertise the connected FWSM interfaces in to EIGRP for access in/out of all my VRF'd subnets. If I need another subnet for each VRF FWSM next hop then I'll have to reditribute a list of statics which I don't really want to do.
 
The reason I am not just using the FWSM as gateway is because I need to run HSRP across 3 different devices (another 6500 in a second suite), and failover FWSM will only give me 1 level of redundancy for those gateways.

Cisco Firewall :: ASA 5505 Expanding A DMZ With VLAN

Jan 30, 2012

On our ASA 5505 We have a DMZ configured to use 2 ports, which are used by the mail and Web servers. So far everything works perfectly and this router has been very stable. Now I need to add more ports in order to accomodate prototype Web servers in the DMZ, but no more ports available on the Cisco. Looking through the ASDM though I noticed the DMZ seems to be configured as "VLAN 5", sure enough with VLAN ID 5. So I tried creating a VLAN with ID 5 in my ProCurve switch, isolated from other VLANs. My theory being that plugging on of the the router's DMZ interfaced onto this VLAN would allow me to add my test servers. Well, this seems to work, but for only a very short time. I can get the landing page from my test server to display, and then everything slows down to a crawl and communication seems to be blocked. Out of curiosity, I tried to put my prod server and email server on the VLAN, together and separately, but the same thing happens. At first, I can ping the machines, then after a few request, everything stops responding.

Cisco Firewall :: VLAN Traffic On ASA 5505?

Aug 15, 2011

I have a Cisco ASA 5505 that I have configured.  The outside interface is vlan 2 and the inside interface is vlan 1.  Port 0 of the ASA is configured to be in vlan 2 and is connected to the ISP provided subnet.  Port 1 is connected to my private LAN subnet.  I have an additional router connected to Port 2 for guest connectivity.  Port 2 is configured to be a member of VLAN 2 so that it can access the ISP provided subnet.  From the device connected to port 2 I can ping the vlan 2 interface address of the ASA and from the ASA I can ping the Default gateway of the ISP provided subnet.  For some reason the router on port 2 cannot ping the default gateway of the ISP provided subnet.  If the vlan were working the same as a vlan in a switch, I would expect to be able to do this. why it is not working or what I can do to get it working?

Cisco Firewall :: ASA 5505 With Base License That Uses 3 VLAN

Jul 17, 2012

I am working on ASA 5505 with Base License that uses 3 VLAN's.
 
-My VLAN 1 is for used for my home network.
-VLAN 2 is connected to the public Internet and my IP gets assigned by ISP dynamically.
-VLAN 3 is DMZ where I will have few VM's that would need access to and from the Internet.
 
I am looking to work with following:

1) 172.16.0.2 that sits on DMZ will need to access public Internet over port 80
2) Permit access from the Internet over port 3389 to 172.16.0.2
3) Permit any host on private VLAN (192.168.0.0 network) to access 172.16.0.2 over the port 3389
4) Permit second VM on the DMZ VLAN let say 172.16.0.3 to access public Internet on all ports. Access in to this host is not permitted.
5) For some reason DHCP hosts are NOT getting DNS (8.8.8.8) entry when IP hets assigned or renew. I have a statements below but it is not working.
 
Also, if ACL rules for VoIP are written correctly. The goal is to permit these ports (SIP related) to access VoIP router. [code]

Cisco Firewall :: S2S VPN Between ASA 5520 And 5505 With 2 Subnets On Different VLAN

May 26, 2013

Site A:
ASA5520
VLAN data               subnet 172.16.10.x/24
VLAN Voice             subnet 10.0.0.x/24
 
Site B:
ASA5505 Base license
VLAN data               subnet 192.168.10.x/24
VLAN Voice (restr)    subnet 10.0.1.0/24
 
The callmanager is located on site A and needs to sent out DHCP-offers to site B through the VPN so the IP-phones can register to the callmanager. I got the VPN up and running for the data-subnet but i can't get traffic through the voice-subnet/VLAN.
 
Can the ASA's do the job or do I need to route traffic before the ASA's on both sides and sent it through the tunnel, configured both subnets as interesting traffic? Ofcourse the last situation I need to upgrade the license for the 5505 to gain more VLAN's.

Cisco Firewall :: Inter VLAN-Routing ASA 5505?

Jul 8, 2012

Ive been readin all over the internet (including this site) trying to figure out if the asa can handle intervlan routing. Im not sure what I am missing on my config to get this to work.  Ive read that it can work and Ive read that it cant work. How to get this to work on my asa 5505.
 
Here is my setup
 
Cable Modem ---> ASA (eth0/0) 
(eth0/2) -->unmanaged switch for LAN connectivity
(eth0/3) --> Access point for wireless LAN connectivty
 
My config is attached
 
What I would like to do is be able to communicate between vlan3(LAN) and vlan4(Wireless LAN)
 
Whats strange is I can RDP between the two vlans but I cant ping or anything else.

Cisco Firewall :: ASA 5505 VLAN Or Trunk Configuration?

Sep 2, 2012

ASA 5505, I got a security plus license which allows multiple VLANs.I want to be able to configure the ASA to allow only RDP session (One way) to another Switch where all the VLANs are. I've attached a pic of what I want but I'm struggling.
 
I looked at documentation saying you should have inside and outside interface but I'm not sure on this scenario.I've configured inside interface on ASA e0/1 and interface VLANs but not sure what to do between ASA and Switch?

Cisco Firewall :: ASA 5505 / Multiple Interfaces In Outside VLAN?

Feb 12, 2013

This is for an ASA 5505 with the base license...I have a situation where I will not have one interface in my outside VLAN, but instead I want to have interfaces 1-7 in my outside VLAN and interface0/0 in my inside VLAN.
 
Is this supported with the Base license, and if so how would I do this?  Do I still just need to assign one IP address to the outside VLAN?
 
Or will I need to upgrade to the Security Plus license and put each interface in a separate outside VLAN, so in essence I would have 7 outside VLANs each with the same security level (0)?
 
My situation is that I have several partner networks that i want to "aggregate" thru my one ASA 5505.  So each outside interface represents a separate partner (outside) network, each of which I want to get to from my inside network.  Hence the many outside to one inside.

Cisco Firewall :: ASA 5505 Losing Outside Interface?

I have a problem where my outside interface stops passing traffic and the only way to resolve the issue is to reload the ASA, the interface never is down it just stops passing traffic. The inside interface never stops allowing traffic to pass as I can get to all my internal servers and shared drives.
 
The firmware is:

Cisco Firewall :: 5505 PAT Between 2 Networks On Same Interface

I'm using asa 5505 with 8.4(2) and have the following problem.I have 2 Networks. each Network has it's own externel Internet-Ip and also Mail-Server.
[code]

Now I want a communication between the two Mailservers with their external Ip-Address.I did a static NAT from ipnt any to int any or also from int routed to int routed, but nothing worked.Packet tracer showed at NAT-Lookup where the externel adress of the second Mailserver is passed: Info Static translate Network1 to Network1
 
But it should show a translation from network1 to network1-external.Due to Security reasons, I cannot paste the whole config.Under 8.0 I did the same configuration with Policy-Nat and it worked.

How To Assign Each Customer To A Vlan

Sep 3, 2012

How do you assign each customer to a vlan ? and what kit do you use at the core to roll out VLANS to each pop? We are thinking of using Juniper kit - putting customers on there own VLAN, and having a managed service like TR-069 on those VLANS.Is it do-able and what does everyone use for a TR-069 server - I've been looking on the net and havent had much joy in finding a server - or is it not as easy as I understand it to be.

Cisco Firewall :: Limit Speed On Port Or VLAN ASA 5505

Aug 7, 2012

We need to have one connection with less internet bandwidth assigned to it than all other other connections. Basically it is a separate conection from all others, incoming just from one switch port and separate VLAN.I know this can be done on the switch by limiting the bandwidth allocated to a port,
 
however, is it possible to have the speed limited down, just before it goes to the internet, ie, on the ASA, rather than doing it on the switch?The firewall is an ASA 5505.

VLAN2 - outside

If I do add all the VLANs above I understand I will probably have to make a trunk port since I only have 5 usable interfaces
